Trans. Troubles After POwerloading?
With the removal of torque management and the quicker shifts with the Powerloader. I was wondering if anyone has had any transmission troubles with their A4s.

Actually, snappier shifts increase the life of the transmission. The manufaturers make em soft and lazy for comfort to the average driver.
But Vette owners are not the average driver!
Snap on!!! :D

Re: Trans. Troubles After POwerloading? (Mitch C)
I've had mine Powerloaded for almost a year now, and drive it pretty hard (including some drag strip time), with ZERO problems...except for increased tire wear! :D

What is it good for to remove the torque management????

The attached Excel sheet is from a trace with a A4 C5 owner who has had lose of performance since he has PCM code worked on.
He felt the car just did not pull very well. He did a PCM scan while driving and the results for this tread was sorted to bring all the cycles the TCC was engaged to the top of sheet showing loss of torque.

Notice this occured during different RPMs.
Now here is a trace that was during WOT and TCC not being triggered.
Notice the higer overall TQ number.

If the TCC is either not working correctly or as in the following PCM trace shows, the TCC code was mucked with by a so called PCM tuner, the Torque management circuit to protect the drivetrain will disengage the converter to where your free wheeling ( T.C not connected to drivetrain) thus you lose overall torque since it is not under engine power.

Re: Trans. Troubles After POwerloading? (Mean Green 2000)
Mean Green,
I think the point that Zr-1 is trying to make is that the PLII is not optimally perfect for a given application. Unless, you have a PCM custom made and dyno tested for your particular application, you will never have it PERFECT. From what I can tell, his experience was less than ours with Steve Cole's Powerloader II. Personally, I am pleased with the less than perfect results that my car has achieved with the PLII. It is so much closer to being perfect than it was.
Thanks you Mr. Cole....The masses are enjoying your products and the smiles that it brings!

Re: Trans. Troubles After POwerloading? (Mitch C)
Mine has been in for three months and 3500 miles. No problems other than tire wear, a bigger smile I can't get off my face :D a slight decrease in gas mileage (you hold down the right pedal all the time and see if your gas mileage doesn't decline :lol: :lol: ), the active handling seems to activate more often, and a faster trip down the drag strip :cheers: :cheers: :lol: :lol: :lol: :lol:

Re: Trans. Troubles After POwerloading? (Mean Green 2000)
I'm no medicine man, so give to me straight Doc....is the PLII good or bad....cause I noticed a very big difference to the plus side :D
Torque management seems to be forgotten and then people do not understand why after having the A4 re-calibrated that they feel the car is not pulling as well as it should.
Other factors could trip off the TCC such as multi misfires, unknown to the end user and thus I always suggest people hooking up a PCM scanner and finding out if their mods ( which includes PCM coding) have an ill effect to TCC and if it does, have their PCM coder correct the problem.
I am not saying to turn off TCC monitor just tune it not to undo the performance gains..

My point was not to any one brand of custom coder but that the TCC (Torque Convertor Clutch) circuit should be considered when tuning or if it has any ill effect to maximum performance as well as the Crankshaft Position Sensor (CKP) and knock sensors.

is a pcm scanner something like autotap...?

thanks...looks like I have a lot to lean yet..... :cheers:

Using a scanner is quite easy and you'll know how well or poor your tuned for performance is without having to wonder.

^^^^ thanks again...any reccomendations on one or the other, can they both monitor the stuff you mentioned?

Re: Trans. Troubles After POwerloading? (team-zr1)
team-zr1,
I wonder if my problem has something to do with the torque management??
My TC often unlocks when I am in 4th and cruise under 2000rpm, then it sometimes locks up again, soemtimes does not.
If it does not, I have to stop and turn off the car, when I start again every thing works well, until I come under 2000rpm in 4th durig cruissing again.
Sometimes it throws the 1870 code then and I´ve seen a 0748???(not sure) code (something with a solenoid) sometimes also. Then I have to clear the codes with AUTOTAP to get the TC lockup again.
No problems in 3rd!!!
That all came after the tranny, 3.42 and TC swap.
I have a vacuum module controlling the shift firmness.
It may be the Hypertech also as I set the tirehight and gears with that??
Hope to find out what it is?!?!?!?!?
Maybe you have an idea?!?!?!?
Thanks,
Michael

Re: Trans. Troubles After POwerloading? (Austrian Vette)
It just might be a problem and the best thing I can suggest is you do some PCM scanning which includes Delivered Torque as one of the functions you monitor and see when TCC is on or off.
Your welcome to e-mail me copies of your traces and I'll let you know what I see.

Re: Trans. Troubles After POwerloading? (Austrian Vette)
Thanks, I´ll come back to your offer when I get my laptop back from my brother and when I figured out how to save and/or print the AUTOTAP datas.
What all things should I scan???
thanks,
Michael
